XML Web Part - Cannot retrieve the URL specified

I am messing with the XML Web Part and I am having issues with itretrieving the xml file off a web server on another computer. If Icopy and paste the xml contents into the XML Editor and copy and pastethe XSL stylesheet into the XSL Editor the content comes up fine.

As soon as I try to link to the XML file it gives me the error:

Cannot retrieve the URL specified in the XML Link property. For moreassistance, contact your site administrator.

I cannot figure out why it is doing this. If I choose Test Link thedata comes up just fine.

If I copy and paste the XML data in and link to the XSL Stylesheet Iget the error of:

The XSL specified by the XSL property or XSL Link property is notvalid, or the XSL file cannot be accessed. Make sure you havespecified a valid XSL style sheet for this Web Part, or if the XSLfile is linked that it can be accessed by the server. For assistance,contact your site administrator.
